First Appearance Trapped

Ben Tennyson is a hero in Ben 10: Samurai World, Ben 10: Revenge of Ghostfreak and Ben 23: Resistance. He first appeared in Trapped. He is a Human from the planet Earth-1213-B.


His looks parallels that of Ben Tennyson (Earth-1213) in Samurai World, but with a blue colour scheme and in Ben 23: Resistance and Ben 10 :Revenge of Ghostfreak, he looks like he does in Ben 10: Omniverse.


In a sense, Ben 23 is the same as Ben 10 is, but without Grandpa Max to guide him, Ben 23 hasn't learnt that not all aliens were evil. To fill the void left by the passing of Max, Ben 23 immersed himself in fame and fortune. Unlike Ben 10, who tries to not let fame go to his head (as it has cost him dearly multiple times), Ben 23 has become overconfident, arrogant, and reckless because of it. He also did not have the same sense of right and wrong and didn't want to use the Omnitrix to fight crime or help others in need. One quirk is the fact that he labels most of his aliens with unoriginal names. Despite having unlocked around 50, (claimed 90) aliens on his Omnitrix, Ben 23 keeps only 23 in constant use.

After meeting his dimensional counterpart, who sets him on the right path, Ben 23 begins to act less arrogant and more heroic.

Ben 23 disliked smoothies. Instead, he prefers gyros from a fast food chain, which he incorporates into a catchphrase: "It's gyro time!" But he started to like them after his encounter with Ben 10.

Powers and Abilities


Ben 23 possesses an Omnitrix with a blue/gold color scheme (reflecting Ben's green/black).

Ben 23's battle prowess is almost entirely self-taught, and like Ben 10, Ben 23 tends to fight recklessly in front of people and often has little to no strategy when fighting his enemies.


Gyros and Endorsments.



Max Tennyson died around the time when Ben received the Omnitrix, and he had to teach himself how to use it.

Without Grandpa Max, he lacks the morals of his other counterpart, and became a rich and famous person over the years.

Ben 23 has movie rights, endorsement deals, and uses aliens to make a lot of money. At this point in time, his greatest enemy was the Intellectuary and has not yet encountered greater enemies like Vilgax.
